434 MR. MARTIN JACOBY ON NEW SPECIES [Nov. 28, 



short and transverse, the sides rounded and broadly flattened, the 

 anterior angles acute but not dentiform, the surface entirely 

 impunctate, testaceous ; scutellum piceous ; elytra with broadly 

 flattened mai-gins, slightly widened at the middle, finely and closely 

 punctured, testaceous, with two broad fulvous transverse bands — 

 one at the base, deeply concave at its lower margin and connected 

 by a sutural stripe with the second band near the ajoex of obliquely 

 subquadrate shape, both bands ai-e interrupted at some distance 

 from the lateral margins and are more or less distinctly edged 

 with piceous, the basal margin especially so ; under side and legs 

 testaceous. 



Hah. Argentine R. and Brazil. 



Not unlike 0. pustulata Jac. in coloration, but the antennae 

 differently coloured, the thorax without a fulvous spot, and the 

 elytral bands of different shape. 



OeDIONYCHIS CATHARINE, sp. n. 



Dark fulvous below, antennae black ; thorax flavous, impu.nctate ; 

 head and scutellum dark fulvous; elytra rather strongly and 

 closely punctured, dark fulvous, a large discoidal ovate patch on 

 each, flavous. 



Length 6 millim. 



Of rather elongate and parallel shape ; the head impunctate, 

 fulvous, deeply grooved between the eyes, the latter large, frontal 

 elevations broad, transverse ; carina blunt and thick ; antennae 

 robust, black, third joint distinctly shorter than the foiu^th ; thorax 

 strongly transverse, the lateral margins distinctly rounded, the 

 anterior angles but slightly j^roduced outwards, scarcely toothed, 

 lateral sulci broad and deep, the surface impunctate, flavous ; 

 elytra with narrow reflexed margins, fulvous, distinctly punctured, 

 the disc occupied by a large flavous ovate patch, with its nar- 

 rowest portion near the suture ; under side and legs dark fulvous, 

 the tibiae and tarsi blackish ; metatarsus very short, claw- joint 

 strongly inflated. 



Hah. St. Catharina, Brazil. 



Of somewhat similar coloration to 0. A-pustulata Jac. from the 

 same locality, but the thorax without fulvous spot, the antennae 

 entirely black, with more elongate joints, and the whole apex of 

 the elytra fulvous ; the thoracic sulci in the present species also 

 are wider and deeper. 



OeDIONYCHIS ocellata, sp. u. (Plate XY. fig. 10.) 



Black, thorax testaceous, with three black spots ; elytra closely 

 and strongly punctured, each elytron with six small flavous 

 spots (1.2.2.1). 



Lengi3h 5 millim. 



Head not perceptibly punctured, the middle black, the sides and 

 the antei'ior poi'tion testaceous, frontal tubercles shoit and broad, 

 strongly raised, carina broad ; antennae rather short and robust, 

 black, the lower iliree joints moi-e or less flavous; third joint more
